Frogs, like all other amphibians, are declining all around the world, in both pristine and protected areas as well as suburban marshes bordered by highways. This decline is due to the combined effects of a number of factors, such as an increase in ultraviolet rays, chemical pollution, habitat destruction, overharvesting, climate change, the introduction of exotic species and the propagation of diseases and fungi. Part of La Mauricie National Park's mandate is to serve as a representative area in the protection and understanding of ecosystems. Monitoring the aquatic frog community is done through visual counts and catching frogs in transects.
